i'l his inv ts i 1 {lorries and other hand boats, canoe I "l aims toprovide an oar propel led ho ins: device w n the rearward movement 's;occasioned by the rear-- \vi inoveinein, of winpleinental handles sothat the boat be properly propelled in the direction the oarsinan withthe ob vious result of enabling the oarsinan to row a in can out theinvention there pro-- vided a pa c at similarlyconstructed units each ofwhich incliiides generally a plate pivoted to the gunwaie o whichismounted a pair othandle members the gears of predetermined ratio. r ii The plate is reversible so that either oi the handle members maydetachahly receive the oar blades so that the heat can be propelled athigh speed necessitating greater effort on the part of the oarsinan, orat low speed requiring less effort on the part of the oarsmanAn'important object of this invention resides in the provision of ancaring device that oi? simple construction and that may be attached tothe gunvvale ot' a boat without in any Way Whatever altering theconstruction of the boat.

With the'foregoing and other objects in view as the nature ot theinvention \vill'be better understood, the same comprises the novel term,combination and arrangement of parts hereinafter more fully shown in theaccompanying drawings and claimed. i

In the accompanying drawings wherein like reterence characters indicatecorrespondin o: parts throughout the several views:

Figure l is a fragmentary plan VIEW otthe rear end of a ron boat or thelike equipped with pair of the caring devices construhted f inaccordance with the invention.

Figure :2 is a fragmentary transverse section through the top board ofone of the boat gunwales disclosing the caring device in sideclevation.- I V p a v Figure 3 is a bottom plan view otthc device perse, the oar blade being removed. 1

Figure 4 is a fragmentary section through ition relates to new anduseful caring devices 'lfor row the boat and upon ier ends thereofhavinginteri'neshing described,

member and the oar blade disclosing more clearly the manner ofdetachableconnection 8 between the member and said oar blades, and Figure 6 is atragmen'tary'plan view of one of the boat gunwales and one of the oaringdevices in this instance the device being re versed from the positionasdisclosed in Figure 1.

Now having particular reference to. the

drawings, A designates a row boator similar hand propelled crafts, WhileB-B designate generally a pair me oaring devices constructed inaccordancewith the present invention as associated with the gunivales ofthe 7 boat directly 5 Etront ot the oarsmans seat The wing deviceconsists of a pair of spaced parallel attaching straps 5- -5 havingopenings therein to permitof their attachment oi the gunivalo of theboat transverselythereof through themedium 0t screws or other similarfasteners. The inner ends of these straps 5-5 are interconnectedby anarcuate bridge piece 7 that extends considerably above the straps '55 toserve as aresting block as will be presently brought out.

The forward ends of these straps 5 -5 are provided with upstanding ears8-8 that are formed with alined openings to provide bearings for thepintle ends 99.ot a rock shaft 10. Thisrock shaft 10 istormed orassociated otherwise Withthe bottom surface and substantiallyintermediate the ends of aright angularlyextending plate 11. P-ivotedupon the top side of this plate 11 at opposite sides of the centerthereof isa pair of intern'leshing gears 12-12, the ratio of which withrespect to each other is preferably two to one. i

Theperiphery of each of these gears is formed or constructed with aradial tubular member 18 to provide an actuating handle or I a holdertor an ear blade 14, the inner end of which is preferably of reduceddiameter and "of a size to prov de a tight ht Within either tubularmember.

Each tubular member is providedat its outer end with a flange and Withopposed openings lose that the said blade id may be secured Withineither tubular member through the medium of a locking pin 1'5,preferably of the readily removable type disclosec in Figure 5. 1 p()bviously the plate i 11 may be pivotally arranged between thesupporting straps 5-5 so that either one of the tubular members 13 maybeemployed astheactuating handle 1 so that when in the position asillustrated in Figured the reverse motions of the innermost tubularmembers will result in the rapid movement of the oar blades, WhereasWhen the devices are reversed as disclosed in Figure 6 a slower motionof the blades Will be had. Obviously, by reason of the pivotalattachment of the plate 11, the oar blades may be readily raised from orlowered into the Water, While when raised the plate may be supportedupon the bridge pieces 7.

In View of the foregoing description when considered in conjunction withthe accompanying drawings itWill be apparent that I have provided highlynovel, simple and e1-1- tieniely useful oa'ring device that is to beused on all hand propelled boats, and even though I have herein shownand described the invention as consisting of certain detail structuralelement-s5 it is nevertheless to be understo'odtiat some changes may bemade therein Without affecting the spirit and scope of the appendedclaim.

Having thus described the invention, What I claim is:

In an caring device of the character described a base member adapted forlon itudinal arrangement upon the gunwale of a boat, a transverselyextending plate pivoted to said base member so that the same may rocklaterally thereon, a pair of intermeshing gears mounted for rotationupon the surface of the plate construction extending radially from eachgear to provide hand and oar receiving sockets, said gears being ofdifferent sizes sons to regulate the sweep of the oar blades,and anarcuate shaped member supported below the inner end of the plate andupon which the plate may ride.

In testimony whereof I aifiX my signature.

CHARLES ARTHUR BILESTINE.
